Lines B and C are perpendicular ⇒ answer C
Step-by-step explanation:
The product of the slopes of the perpendicular line is -1
The slopes of the parallel lines are equal
The slopes of two lines are and
1. If × = -1, then the two lines are perpendicular
2. If = , the the two lines are parallel
The equation of a line in slope-intercept form is y = m x + c, where m is
the slope of the line
Line A: y = x + 2
The slope of the line is =
Line B: y = x + 7
The slope of the line is =
Line C: y = 2 x + 4
The slope of the line is = 2
Line D: x +
The slope of the line is =
∵ =
∵ = 2
∵ × 2 = -1
∴ Line B and Line C are perpendicular because the product of their
slopes is -1
Lines B and C are perpendicular

Answer:
0,4
Step-by-step explanation:
Answer:
5. D 6. B 7. A
Step-by-step explanation:
it is just like a square all sides are the same
Answer:
1) first two (A & B)
2. -1,533
Step-by-step explanation:
Sum to infinity is finite when
-1 < r < 1
Option 1: r = -¼
Option 2: r = 27/81 = ⅓
Option 3: r = 3/2
Option 4: r = 17.75/7.1 = 2.5
a = -3
r = -6/-3 = 2
S9 = -3 × (2⁹ - 1)/(2 - 1)
= -1533
